Get aggregate batch progress

Returns the company-scoped aggregate for sessions created with the same `batchRef`. A session becomes processed when its submission reaches `failed`, `review`, `approved`, `synced`, or `capture_quality_blocked`. Capture-quality blocks are included in `counts.failed`; synced rows are included in `counts.approved`. When `processed` equals `total`, Steve waits until the newest session in the batch is at least five minutes old before marking the batch completed and emitting `batch.completed`. A newer session resets the grace check. A client pause longer than five minutes can therefore complete the batch before later uploads arrive; later sessions increase the counts but do not emit a second completion event.
